Syntax 2: For lines in a graph
Description
Specifies the style and width of a series’ lines in a
graph.
Applies to
Graph controls in windows and user objects, and graphs in
DataWindow controls objects

controlname.SetSeriesStyle ( { graphcontrol, } seriesname, linestyle, linewidth ) |

Argument |
Description |
|---|---|
|
controlname |
The name of the graph in which you want to set the line |
|
graphcontrol (DataWindow control only) (optional) |
A string whose value is the name of the graph in the |
|
seriesname |
A string whose value is the name of the series for which |
|
linestyle |
A value of the LineStyle enumerated datatype. Values Continuous! Dash! DashDot! DashDotDot! Dot! Transparent! |
|
linewidth |
An integer specifying the width of the line in |
Return value
Integer.
Returns 1 if it succeeds and -1 if an error occurs. If any
argument’s value is null, SetSeriesStyle returns null.
Usage
Data points in a series can have their own style settings.
Settings made with SetDataStyle set the style of individual data points
and override series settings.
The graph stores style information for properties that do not
apply to the current graph type. For example, you can set the fill
pattern in a two-dimensional line graph or the line style in a bar
graph, but that fill pattern or line style will not be visible.
For a graph in a DataWindow, you can specify the appearance of a
series in the graph before PowerBuilder draws the graph. To do so,
define a user event for pbm_dwngraphcreate and call SetSeriesStyle in
the script for that event. The event pbm_dwngraphcreate is triggered
just before a graph is created in a DataWindow object.
Examples
This statement sets the line style and width for the series named
Costs in the graph gr_product_data:
|
1 2 |
gr_product_data.SetSeriesStyle("Costs", & Dot!, 5) |
